This webinar episode is a highly visual “peek under the design engineer’s tent” revealing the reasons for and consequences of fabricating structural components by welding wrought steel pieces together.  And… why, after all has been invested in the fabricated design, there is almost always a significant return on investment when starting all over with a casting design.

Conversion of fabrications to castings is a large market segment dominated by ductile iron casting conversions… and that is good for all concerned.  But… when the combination of high stress, allowing deflection, long cyclic life, and low mass is the requirement, steel castings are unsurpassed.

Why steel castings dominate, when capability is really important, is explained with simple metallurgical and structural design reasons…. and a case study.  The case study is a capstone for Episodes 1 through 5, showing how Castability Geometry in steel casting design works.  And, a glimpse of a future episode explaining the overlay of Structural Geometry on the Castability Geometry foundation.
